SPIEGIFECATIQN forming part of Letters Patent No, screen, dated December 1, 1885.

Application filed June 12, 1884. Serial No. 134,677. (No model.)

To aZZ whom it may concern.-

Be it known that I, ELLIOTT E. FURNEY, of the city of St. Louis, in the State of Missouri, haveinvented a certain new and useful Apparatus for Checking the lVaste of lVater, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This device causes the How of water to cease after a given quantity has passed through the discharge-spout, whether the device for turning on the supply is returned to the position in which it was found after opening the apparatus or not.

It consists of a case h aving two chambers separated bya diaphragm, through which passes a valve-stem carrying a valve at each end, of which the diaphragm forms the seats. Around the valve-stem are a number of passages, (or a single passage,) through which the water passes from the chamber in communication with the supply-pipe to the other chamber, which is in communication with the dischargepipe. The water-passage is closed when either valve reaches its seat. There is a duct controlled by a valve, through which the water maybe allowed to fiow from one chamber into the other. One of the valves of the stem is made in the form of a piston, and fits the cylindrical chamber, so as to nearly close communication between the parts of the chamber above and below the valve-piston.

Figure 1 is an elevation of the apparatus. Fig. 2 a section at 2 2, Fig. 8, showing the valves ascending, the duct-valve being open. Fig. 3 is a detail section at 2 2, Fig. 8, showing the lower valve closed against its seat, and Fig. 6 is a similar section, showing the upper valve closed upon its seats. Fig. 4 is a section at 2 2, Fig. 8, showing the valves descending. Figs. 5 and 7 are sections at 2 2, Fig. 8, illustrating the action of the automatic valves whenthe course of the water is upward. Fig. 8 is a transverse section at 8 8, Fig. 5. Fig. 9 is a modification showing the duct connecting the chambers passing through the stem of the automatic valves. Fig. l0is a transverse sec tion at 10 10, Fig. 9.

A is a case constructed in any suitable manner and of any suitable material, as castiron.

B and O are the induction and the edluction (or discharge) nipples.

I will first describe the device as shown in Figs. 2 and 4, in which the water passes downward through the valve-seat diaphragm, B being the induction, and O the cduction, nipple or passage.

D is a diaphragm perforated centrally for the passage of the stem E of the two automatic valves F and G. The central orifice of thefgiaphragm has a number of grooves forming channels (Z, through which the water passes freely whenneitherof the valves is closed; but when either of the valves is closed upon its seat on the diaphragm the passages d are stopped.

H and I are the cylinders in which the valves F and G work, the upper valve, F, fitting as a piston in its cylinder, the fit being so tight as to prevent the free passage of water between the piston-valve F and the cylinder. A limited quantity of water isallowed to pass through or around the piston-valve, for a purpose to be hereinafter explained. This may be provided for by making the piston. to fit somewhat loosely in the cylinder or by boring a small hole, f, through the piston, as shown in the drawings. The lower end of the cylinder H does not reach the diaphragm 11); but there is a passage between them all around communicating with an annular chamber, J, extending around the lower end of the cylindcr. The induction-passage l3 communicates with this annular chamber, and thus with the interior of the cylinder H below the pistonvalve. The interior of the cylinder H has at its lower end a beveled valve-seat, h, acting, in conj unction with the valve F, to close communication between. the interior of the cylinder H and the induction-passage B. At the same time the passages cl and f are closed by the same valve, so that there is no communication between the lower cylinder, I, and the induction-passage, and no communication between the parts of the cylinder H which are above and below the piston-valve.

K is a water pipe or duct extending from the upper part of the cylinder H to the upper part of the cylinder I.

L is a cock in the duct, by which it may be closed.

The valves F G may have leather, rubber, or other faces F G, or may be fitted to their seats with ground joints.

The head H of the cylinder H is made flat to fit the flat upper side of the valve F and form a seat therefor, so that when the valve is in its upper positon no liquid can escape through the passage or duct K, nor between the valve and the cylinder, or through the passagef, (in the valve.)

The normal position of the cock L is open, as seen in Fig. 2, the valves F and G being in 7 their upper position, so as to prevent any water passing into chamber I either through passages (Z or K. When it is desired to draw water, the cock L is closed. The valves descend by the pressure of water above them as fast as the water can pass through the passage f. (See Fig. 4.) The water flows through the passages (Z and eduction C until the valve F reaches its seats h D, when the flow of water ceases, the passage K being closed by the cock L and the passages d andf closed by the contact of valve F with its seat D. Now, to draw water, itis needed first to open the cock L and then'to close this cock. On opening the cook the valves F and G fly to their upper position, and on closing the cook the water to a given quantity flows out, as aforesaid. It

will be seen thatthe top of valve F has greater.

area than its under side, so that as water passes above it both valves will be forced downward by water-pressure. If the cock L is left open after the discharge of the water contained in the cylinder H above the valve F, there is no further discharge, as the passages K and f are closed by the valve F and its seat, and the passages d are closed by the valve G.

I will now describe the action of the device when the nipple O is coupled with the supply pipe and the water discharges through the orifice B. In this case, when the cock L is closed, the pressure from beneath the valve G lifts the valves, and when the cock is open the pressure on top of the valve F depresses the valves. The lilting of the valves can only take place slowly,as they are only allowed to ascend by the escape of water from above the valve through the passage f, or around the valve, whereas the descent of the valves on opening the cock is rapid, as the water has free passage to the upper part of cylinder H through the duct K.

It will be seen that the manipulation of the cock L is the same in both cases,whether the water escapes through 13 or through 0, the water in either case flowing for a limited time when the cock L is closed, after having been opened.

The direction of the water-currents is indicated by arrows, and the direction of the movement of the valves is shown by an arrow upon the valvestem.

In Figs. 2 and 4 the water enters at B and escapes at 0. Fig. 2 represents the valves in the act of rising as the cockL is opened. Fig. 4 represents the valves descending when the cock L is closed.

In Figs. 5 and 7 the water enters the apparatus at O and escapes at B.

Fig. 5 represents the valves descending as the cock L isopened, and Fig. 7 shows the valves ascending, the cock L being closed.

It is not essential to the invention that the duct leading from the upper part of the cylinder H to the cylinder I should be located in any particular place or position, it being only essential that there should be a way for the water to pass to and fro between the cylinder I and the part of the cylinder H above the valve F, and that the same should be controlled by a valve or cock.

As one of many possible modifications, I show the duct passing through the stem E of the valves F G. (See Figs. 9 and 10.) The stem E has an axial bore, 0 e, from top to bottom, the upper part, c, of the bore being of greater diameter than the lower part, 6, and between the parts is a conical valveseat, eiof the conical valve L. This valve has a tubular stem, L, turning in the part 6 of the bore. From the inside of the tubular stem a passage, Z, extends through the face of the valve, said passage being closed by the valveseat when the valve is in the position shown in Fig. 9; but when the valve is turned about onehalf around, the passage Z is brought in conjunc tion or line with a passage, 0, in the valveseat, and communication is opened between the cylinder I and the part of the cylinder H above the valve F.

As a means of operating the valve L,I show a stem, M, passing through astuffing-box, N, and having at the lower end a cross-bar, m,

whose ends occupy vertical grooves Z, so that the tubular stem L is made to turnwith the stem M, while at the same time the valves F and G, with their connecting stem E, are left free to move up and down, while at the same time the stem M has no vertical movement. The stem E is prevented from turning with the valve L by a feather, e that works in a seat made in the diaphragtn'D.

The operation of this device is similar to that described in relation to Figs. 2 and 4:, as the valve L of this device is the exact equivalent in its office to the cock Lof those figures, and the axial passage through the valve-stem E serves the exact purpose of the duct or passage K.

I claim 1. Two chambers or cylinders in connection, respectively, with the water supply and discharge, and separated by a diaphragm through which passes a connecting-stem of two valves, one of which has a small passage and works as a piston in one chamber or cylinder, the other valve working free in the other chamber or cylinder, a passage for wa ter through the diaphragm from one chamber ICC to the other, elosable by either of the valves, and a duct controlled by a cook or valve leading from one chamber to the other.

2.
